Slip Moss Stitch

Hi, I am working on my first jumper for my cousins first daughter.
But the neck line is a slip moss stitch.
I have no idea how to work this, and I am the only knitter among my family and friends.
Any assistance on how to make this up would be wonderful, she is due Christmas day so she will need it to stay snuggly warm.


Slip Moss stitch:
Row 1: *K1,yf,sl1,yb; rep from * to end of row
Row 2: *P1,yb,sl1; rep from * to end of row

I found it here.

Thank you! This is going to help me so much!
